Title: Scan converter
Inventor: WATANABE TADAYOSHI
IPC: G09G5/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce deviation between upper/lower display images by starting timing of a transfer start between two sets of memories at the timing of a synchronizing signal of an NTSC(national television system committee) image signal and making a transfer speed the same as a read-out transfer speed of an image display. SOLUTION: The image signal N digital converted by an A/D converter 1 is written in a first memory 3 at the NTSC synchronizing signal Ns inputted through a control means 2, and is transferred from the first memory 3 to a second memory 4 synchronized with the timing of the NTSC synchronizing signal Ns. Then, a read-out NTSC image signal isn't outputted faster than a write-in NTSC image signal N. Thus, the transfer speed from the first memory 3 to the second memory 4 becomes the same as the read-out transfer speed of the image signal H of a host system. Then, the NTSC image signal N read out from the first memory 3 and written in the second memory 4 is read out by the synchronizing signal Hs of the host system inputted through the control means 2.

Title: Pulse detection circuit
Inventor: KANDA KAZUHISA
IPC: G01S17/10
Filed: 1995-03-06
Abstract: PURPOSE: To provide a pulse detection circuit in which the back-scattering optical pulse of a pulse laser transmitter-receiver or the like is removed surely. CONSTITUTION: A received signal 1 is waveform-shaped 2, and a signal pulse in two pulses each is generated by a flip-flop 3. A single multiplexer 4 generates one pulse at its rear edge. The width of the single pulse is narrow when a backscattering optical pulse is mixed. Since it is wide (a reflected optical pulse cycle) when the backscattering optical pulse is not mixed, it is monitored by a pulse width judgment circuit 5 so as to form a gate signal which has removed the backscattering optical pulse. The gate signal becomes the extraction signal of a target reflected pulse by a signal processing part 7 via a correlator 6. The signal processing part 7 extracts only the target reflected pulse from the received signal 1, and a DC current which is proportional to its amplitude is outputted.

Title: Time axis correcting device
Inventor: SUMI TAKAO
IPC: G11B20/10
Filed: 1984-03-09
Abstract: PURPOSE:To prevent deterioration of a playback video signal in phase by generating a sample pulse only when a playback color burst signal is present. CONSTITUTION:The output of a VCO5 is applied to a pi/2 phase shifter 11, whose phase output is inputted to a synchronous detector 12. A burst-gated playback signal is applied to the other input and its detection output is inputted to an AND gate 15 through a waveform shaper 14. The output of a generator 9 is applied to the other input of this gate 15 and an S/H circuit 7 performs sample holding operation with the output of the gate 15. The synchronous detector 12 detects whether the playback burst signal is present or not and generates and supplies a gate signal for the gate 15 to the S/H circuit 7 only during the presence period. The gate 15 is closed in other periods, so the S/H circuit 7 holds the last error signal without performing sampling operation and the signal is used as the control signal of a variable phase shifter 10. Consequently, the generation of a time-axis error signal is prevented owing to the absence of the playback burst signal or malfunction of a PLL circuit.
